An electroscope is charged by touching it with a negatively charged rod. The electroscope leaves spread apart and the rod is removed. Then another, negatively charged rod is brought near the top of the electroscope without touching. What happens?
A. You are unable to make the observation because the rod is attracted to the top of the electroscope causing them to touch after all.
B. The leaves do not change their position.
C. The leaves move closer together.
D. The leaves spread further apart.
B & C are not right. Totally lost on this
Homework Answers
here,
due to induction of charges
more negative charge will be inducted at the leaves
hence, they move further apart
the correct answer is
D. The leaves spread further apart.

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

Two students each bring a charged PVC rod near and electroscope. In each case another student touches the electroscope with their finger and then removes it. The only difference between the two situations is in where the student holding the PVC places it next to the electroscope. The first student holds the PVC near the ball on the top of the electroscope, as shown in the figure below. The second student holds the PVC next to the leaves". What will...

Metal spheres 1 and 2 are touching. Both are initially neutral. The charged rod is brought near without touching the spheres. The charged rod is then removed. The spheres are separated by an external agent. Afterward, the charges on the spheres are: Q_1 is + and Q_2 is +. Q_1 is + and Q_2 is - Q_1 is - and Q_2 is +. Q_1 is - and Q_2 is -. Q_1 is 0 and Q_2 is 0. Explain your choice:...
